My second unit, the first lasted three years. Caught a lot of Mosquito's.
Bought a new one April 2013, trouble keeping it running. CO2 cleared lines before and after every use, sometimes with two cartridges. Machine starts up occasionally, shuts down in a day or two. Re-positioned, cleaned vents, changed everything including purchasing gauged propane tank valve.
Breakdowns continued. Contacted customer support, no help at all, no suggestions other than the few on the website.
Finally I found a small pin-sized "vent"? hole in the metal device attached to the rubber propane line where it attaches to the propane tank. Used a safety pin to clear that hole and, wallah!!, the machine has now been running for six days!
No info about this in troubleshooting, customer assistance and never heard about it at their customer service.
Catches when it runs, trouble is keeping it running. Never buying another one.
